Connect Web.de to Perplexity

Updated 1 November 2026

Yes — Perplexity can read, search and reply to your Web.de through Mailopoly. Connect Web.de to Mailopoly over IMAP with your normal Web.de password, once IMAP is enabled, add Mailopoly to Perplexity as a custom connector, sign in and ask. One connection covers Web.de and every other account you own. You use your normal Web.de password, but POP3/IMAP access has to be switched on in Web.de settings first — it's off by default.

Before you start

A Mailopoly account — 7-day free trial, no credit card.
You use your normal Web.de password, but POP3/IMAP access has to be switched on in Web.de settings first — it's off by default.
Perplexity Pro, Max or Enterprise — custom connectors aren't on the free plan. On Enterprise, an admin allows custom connectors first.

Connect Web.de to Perplexity in three steps

1 Connect Web.de to Mailopoly

Start a Mailopoly account at mailopoly.com/sign-up — 7-day free trial, no credit card.
In Web.de webmail, open Einstellungen → POP3/IMAP Abruf and enable IMAP.
In Mailopoly choose Add email account, enter your full Web.de address and your normal Web.de password.

2 Add Mailopoly to Perplexity

This part is the same whatever you connected in step 1.

Add Mailopoly to Perplexity

These steps are taken from public documentation, and we haven't yet checked each one in Perplexity ourselves. If a label doesn't match what you see, Perplexity's own help page, linked below, has the current wording.

In Perplexity, open Account settings → Connectors.
Choose + Custom connector at the top right, then Remote.
Name it Mailopoly and enter https://fastapi.prod.aws.mailopoly.com/mcp-server/ as the MCP Server URL. For Authentication choose OAuth 2.0 — there's no client ID or secret to fill in, Mailopoly registers Perplexity itself — and for Transport choose Streamable HTTP.
Tick the box confirming you understand the risks of custom connectors, choose Add, then click the Mailopoly card to sign in.
Sign in with your Mailopoly account, then choose what Perplexity is allowed to do. Reading, making changes and sending are separate permissions.
Back in Perplexity, ask.

Perplexity takes Mailopoly as a custom remote connector, so the only thing to paste is one address. Custom connectors are available on Perplexity Pro, Max and Enterprise; on Enterprise, an admin has to allow them for the organisation first.

3 Ask about your Web.de

Whatever you've connected to Mailopoly is what your assistant can reach. Some things people ask on day one:

Was ist heute Wichtiges in meiner Web.de Cleanbox? (Mailopoly answers in your language.)
Find the insurance letter in my Web.de mail and tell me the deadline.
Reply to the last message from the Vermieter from my Web.de address.

Web.de server settings

Mailopoly fills these in for you when you enter your address. They're here in case you need to check them or your provider uses something unusual.

IMAP server	imap.web.de
Port	993
Security	SSL/TLS
Username	Your full email address
Password	Your normal Web.de password

What Perplexity can do with Web.de through Mailopoly

Search Web.de — and every other account you own — in one question. By sender, date, topic, or the half-remembered phrase somewhere in the body.
Read your Cleanbox, not your whole inbox. Mailopoly sorts Web.de as it arrives: personal and important mail in Cleanbox, promotions and newsletters in Other. Ask for either.
Summarise a thread, a day or a week. "What did the school send this week?" comes back as an answer, not a list of links.
Reply from your Web.de address, in your voice. Save a draft to Mailopoly for review, or send — sending is a separate permission and a confirm-first action.
Schedule a send for later, and cancel it if you change your mind.
Pull out invoices, events and deliveries. Amounts and due dates, calendar invitations, parcel tracking — extracted on arrival and added to My Day.
Find an attachment. Every attachment from Web.de lands in PolyBox, so "find the PDF the accountant sent" just works.
Unsubscribe, snooze, file and mark read from the chat, on whichever account the mail belongs to.

Reading, making changes and sending are separate permissions you grant when you connect, and you can revoke Perplexity at any time from Settings → Security in the Mailopoly app. More on the security page.

What goes wrong with Web.de, and the fix

IMAP is off until you enable it. A correct password still fails while POP3/IMAP retrieval is switched off.
If two-factor authentication is on, your normal password will be refused and you'll need an app password from your provider's security settings.
The help page is in German. The setting is under Einstellungen → POP3/IMAP Abruf.
No + Custom connector button in Perplexity: custom connectors need Perplexity Pro, Max or Enterprise. On Enterprise, ask your admin to allow custom connectors for the organisation.
The Mailopoly card says it isn't connected: adding the connector doesn't sign you in. Click the Mailopoly card in Account settings → Connectors and finish the Mailopoly sign-in.
Perplexity can't reach the server: check the address is exactly https://fastapi.prod.aws.mailopoly.com/mcp-server/, Authentication is OAuth 2.0 and Transport is Streamable HTTP, then remove the connector and add it again.
